CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation-in-part of U.S. application Ser. No. 13/253,174 entitled “Electronic Messaging Systems” filed Oct. 5, 2011, which claimed the benefit of U.S. Provisional Patent Application No. 61/390,179 entitled “Electronic Messaging Systems” filed Oct. 5, 2010, which are hereby incorporated herein in their entirety.

BACKGROUND

Current messaging systems, such as Facebook and e-mail messaging systems, are focused on facilitating communication between users that know each other. For example, Facebook allows users to quickly send personal updates to multiple individuals who have been added to the user's list of “friends” over time.

In certain situations, it would be desirable to communicate messages to recipients on the basis of the recipients' interest in a particular location rather than the recipients' preexisting relationship with the sender of the message. This would allow users who have an interest in a common geographical area, but who do not necessarily know each other, to share information regarding the area. Various electronic messaging systems described below provide such functionality.

SUMMARY

In various embodiments, a computer system for facilitating communications between users is configured for: (A) receiving, from a first user, one or more user watch area attributes; (B) using the one or more user watch area attributes to define a watch area; (C) receiving, from a second user, a message associated with a particular geographical location, wherein the second user has indicated that the message should be associated with the particular geographical location; (D) determining whether the particular geographical location is located within the user watch area; and (E) at least partially in response to determining that the particular geographical location is located within the user watch area, subscribing the first user to a thread of messages that includes the message.

In various embodiments, a computer system for facilitating communications between users is configured for: (A) receiving, from a first user, one or more first user watch area attributes; (B) using the one or more first user watch area attributes to define a first watch area; (C) receiving, from a second user, one or more second user watch area attributes; (D) using the one or more second user watch area attributes to define a second watch area; (E) at a first particular time, receiving, from a third user, a first message within a particular message thread, the first message being associated with a first geographical location; (F) determining whether the first geographical location is located within the first user watch area; (G) at least partially in response to determining that the first geographical location is located within the first user watch area, transmitting the message thread to the first user; (H) at a second particular time occurring after the first particular time, receiving, from the first user, a second message within the message thread, the second message being associated with a second geographical location; (I) determining whether the second geographical location is located within the second user watch area; and (J) at least partially in response to determining that the second geographical location is located within the second user watch area, transmitting the message thread to the second user.

DETAILED DESCRIPTION OF VARIOUS EMBODIMENTS

Various embodiments now will be described more fully hereinafter with reference to the accompanying drawings. It should be understood that the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout.

An electronic messaging system according to various embodiments comprises: (1) one or more computer servers (referred to collectively herein as “the system server”); (2) one or more user client devices on which a user client software program is installed; and (3) one or more communications networks for facilitating communication between the system server and the system's various user client devices. In particular embodiments, the user client devices may include, for example, a portable computing device (e.g., a laptop computer, a tablet computer, a cellular phone, or a GPS unit). User client devices may also include other types of computers, such as desktop computers.

In particular embodiments, the electronic messaging system is adapted for facilitating communication between a group of users by allowing each of the users to post and receive messages on one or more user client devices. FIGS. 1-3 show exemplary displays of such a user client device. As may be understood, for example, from FIGS. 1-3, users may post a message 140, 141 within a particular message thread 132 and associate the message with a particular geographic location (e.g., by clicking on the particular geographic location on a map 110 that is displayed on the user's client device). The message is then delivered to any other users that are currently subscribed to the thread.

As shown in FIG. 1, in various embodiments, users may select and/or define a geographical zone of interest 125-128, which is referred to below as a user watch area. In particular embodiments, when a particular user watch area is in place for a first user and a second user posts a message and associates the message with a particular geographic location (a post location) within the particular user watch area, the messaging system automatically subscribes the first user to the message thread that is associated with the second user's message. This allows the first user to read, and contribute new messages to, any threads of messages that are associated with the first user's watch area. As shown in FIG. 1, in various embodiments, a user may read a particular message by selecting an icon 115 that indicates the particular location at which the message was posted.

The user watch area may be, for example: (1) a stationary watch area; or (2) a roaming watch area that is defined relative to the position of a movable object (e.g., a person or a particular user client device). For example, as discussed in greater detail below, a stationary user watch area may be defined as a substantially circular geographical area having: (1) its center at a particular static location (e.g., the user's home); and (2) a particular radius. Similarly, a roaming watch area may be defined as a substantially circular geographical area having: (1) its center at the location of a particular user client device (e.g., as defined by a GPS unit associated with the client device); and (2) a particular radius. Such a roaming watch area may, for example, allow a traveling user to monitor and contribute to message threads that are relevant to the user's immediate surroundings.

In particular embodiments, a user may define the shape of a particular user watch area in any of a variety of different ways. For example, the user may define the shape of the watch area by, for example, drawing the user watch area on a map displayed on a display screen associated with the user's user client device. In various embodiments, the system is adapted so that the user may define the shape of the watch area by, for example: (1) specifying both a center of a circular watch area and the desired radius of the watch area; (2) selecting various points that define a polygon-shaped watch area; or (3) drawing the watch area on a display screen.

In certain embodiments, the system may be configured to allow the system to automatically and dynamically determine an appropriate size and shape for the watch area. For example, the system may be adapted to dynamically modify the size and shape of the watch area based, for example, on such factors as: (1) the population density of an area that is within and/or adjacent the current watch area; (2) the number of message postings within an area that is within and/or adjacent the current watch area (either at a particular point in time, or over a predetermined period of time); and/or (3) any other suitable factor.

As a particular example, the system may automatically increase the radius of a circular roaming watch area in response to the watch area moving from a relatively densely populated area to a relatively sparsely populated area. Similarly, the system may automatically decrease the radius of a circular roaming watch area in response to the watch area moving from a relatively sparsely populated area to a relatively densely populated area.

As another example, the system may automatically increase the radius of a circular roaming watch area in response to the number of message postings within the watch area decreasing below a pre-defined number of messages. For example, in response to determining that a number of current message postings within the watch area is below a predetermined threshold number, the system may automatically expand the size of the watch area until the watch area includes the desired number of messages. Similarly, the system may automatically decrease the radius of a circular roaming watch area in response to the number of message postings within the watch area increasing above the pre-defined number of messages.

In other embodiments, the system may automatically change the general shape of the watch area so that it captures a desired number of messages and/or satisfies other pre-determined criteria. For example, the system may change the watch area from a generally circular shape to a generally oval shape so that it includes and/or excludes certain message postings.

The system may also use the techniques described above to automatically adjust the watch area's size or shape in response to the number of messages posted during a particular time period: (A) being higher or lower than a particular threshold; or (B) changing by a predetermined amount.

Watch Roulette Feature

In various embodiments, certain messages and/or message threads (“threads”) may be associated with a particular “channel” of communication. This allows a user to further filter the types of treads that the system will automatically subscribe a particular user to based on whether the threads are associated with a particular channel of interest. For example, in a particular embodiment, the user may specify that they only wish to subscribe to threads that are posted on a “tennis” channel. In one example, the system would only subscribe the user to threads that: (1) are specifically associated with the tennis channel; and (2) satisfy the geographical posting requirements discussed above. This might allow a user, for example, to easily contact and communicate with other users who are in the user's watch area (e.g., as defined, for example, as a circular area having a 2-mile radius centered at the user's home) who are interested in playing tennis.

In particular embodiments:

-   -   The system server maintains a set of channel records with an id         and description, including a public channel.     -   Users are granted access to specific channels. By default, users         only have access to the public channel.     -   When a user creates a new thread, the user client allows the         user to specify which channel the thread should be associated         with.     -   The channel for all messages within a thread is determined by         the root (first) message for that thread.     -   When a user client requests thread data from the system server,         the system server restricts the returned thread data to those         that belong to channels that the user has access to.

Watch Roulette Feature

In various embodiments, the system is adapted to allow users to explore (e.g., in a substantially random manner) message threads that are not associated with any of the user's normal watch areas. In particular implementations, in response to receiving a request from a user to execute the watch roulette feature, the system randomly identifies a thread of messages and displays the thread to a user. In particular embodiments, the user may specify predetermined criteria that the thread must satisfy. For example, the user may specify that any thread to be displayed must: (1) include a message that is associated with a location that is within a predetermined distance (e.g., 20 miles) of a specified location (e.g., the user's current location or another location); and (2) have been updated within a specified period of time (e.g., within the last hour). In particular embodiments, the system is adapted to allow the user to repeatedly execute the watch roulette feature in order to quickly survey the landscape of conversations that are occurring within a particular area within a particular time period.

In certain embodiments, the system is set up to prohibit users from replying to threads that are viewed using the watch roulette feature, unless the thread would have otherwise been visible to the user through one of the user's other watches. However, in other embodiments, users may reply to any threads displayed using this feature.

Automated Message Posting

Although messages are described elsewhere in this disclosure as being originated by a human user (e.g., by a person typing a message on their cell phone or other portable or non-portable electronic device), it should be understood that, in other embodiments, messages may be originated automatically by a computer system. For example, messages may be posted by a client computer that has access to certain events and the locations of those events. In particular embodiments, the client computer may be adapted so that, in response to the occurrence of a particular event, the client computer automatically posts information regarding the particular event on a map at a specific post location that corresponds to the event.

As a specific example, a central home alarm monitoring system may be adapted to monitor multiple homes for the presence of one or more alarm codes that may be automatically generated, for example, when a door or window within the home is opened while the home's alarm system is activated. In a particular embodiment, the home alarm monitoring system is adapted to post an appropriate alert message at a post location that corresponds to the position of the home on a map. This may serve to alert users, who are monitoring a watch area that includes the home, that the home's burglar alarm has been triggered. This may allow those in the immediate area to seek, or otherwise provide, appropriate assistance.

It should be understood that this type of automated message posting functionality may be used in a variety of contexts to automatically alert users of the occurrence and location of a particular event. Other examples of such events include inclement weather activity (e.g., tornados, hail or lightning), crime bulletins, and other types of events.

General Comments

The following comments apply to certain (but not necessarily all) specific embodiments of systems described in this document. It should be understood that some embodiments may include some of the features below and not others. Other embodiments may not include any of these features. Listed features:

-   -   A user with multiple user client devices can have multiple user         client roaming watch areas.     -   For each user client device, a user may choose whether the user         client creates and maintains a roaming watch area for that         particular user client.     -   The user client will keep user client roaming watch area data on         the system server in sync.     -   The user client will continuously monitor the user client device         GPS location and update the corresponding user client roaming         watch area on the system server.     -   Although user client roaming watch areas can be constantly         changing, user client roaming watch areas are, in various         embodiments, treated the same as static user watch areas by the         system server.     -   A user client roaming watch area represents a standing request         to receive notifications for any updates to message threads that         touch that area.     -   In various embodiments, user clients stay in sync with the         system server both in terms of configuration data (e.g., user         watches) and message data (the various messages that the user is         interested in). As shown, for example, in FIGS. 1-4, user         clients may, for example, show users a current snapshot of the         data the user has expressed interest in.     -   In particular embodiments, user interest in a particular thread         or post location is deterministic (e.g., completely         deterministic)—the system knows which users have interest in a         particular thread and which users don't. The system enforces a         consistent set of rules (that users can understand and depend         on) to determine interest.     -   A single user can be associated with multiple clients. For         example, a single user may be associated with client         applications on the user's iPhone, iPad, and laptop computer.     -   In various embodiments, notification data gets “pushed” from the         system server to user clients in following manner:         -   When the system server detects that a new message within a             thread is of interest to a user, the system sends a             notification to each user client for the user (e.g., user             clients on the user's iPhone, iPad, and laptop computer).             -   The notification contains enough information to alert                 the user immediately that new data is pending and what                 the identifier of the new thread is.             -   When the new thread data is actually retrieved from the                 system server can vary. For example:                 -   If the user client is already running, the user                     client will retrieve the data immediately.                 -   If not, the user has been alerted and will see the                     updates next time they run the user client.             -   In various embodiments, user clients sync with the                 system server every time they start or detect updates.

Specific Examples

Various steps that are executed during of the operation of a system according to a particular embodiment are described below with reference to FIGS. 5-9. In this example:

-   -   User A is associated with watch area A1 and user client A1     -   User B is associated with watch area B1 and user client B1     -   User C is associated with watch area C1 and user client C1     -   User D is associated with watch area D1 and user client D1     -   User E is associated with watch area E1 and user client E1     -   User F is associated with watch area F1 and user client F1     -   User G is associated with roaming watch area G1, user client G1,         and client device G1 -device. (User client device G1-device is         GPS-capable and user G has enabled roaming as watch area         G1-roaming).

Step 1: A first thread T1 is created and posted as follows:

-   -   (A) User A posts a new message M1 and specifies a post location         PL1 for this message. (See FIG. 5). User A may specify the post         location either manually (e.g., by specifying a location on a         map displayed on User A's user client device or by specifying         that User A's current location should be used as PL1). Message         M1 is not a reply so it becomes the first message in thread T1.     -   (B) The system establishes a subscription A-T1 which will cause         the system to automatically send user A any updates to thread T1         (which may include, for example, any new messages that are         posted to this message thread).     -   (C) PL1 is within user B's watch area B1. Because of this, the         system notifies user B's user client B1 that thread T1 is of         interest to user B.     -   (D) User B's user client B1 requests thread T1 data from the         system server and presents thread T1 to user B (e.g., by         displaying the text of the thread T1 on the user client device         on which user B's user client B1 is installed).     -   (E) The system establishes a subscription to thread T1         (subscription B-T1) for user B.     -   (F) The system determines PL1 is not within watch areas for         users C-G, and therefor does not take any further action in         regard to notifying users C-G of this thread.

Step 2: a first reply to thread T1 is created and posted as follows:

-   -   (A) User B reads thread T1 on user client B1.     -   (B) User B replies to thread T1 with new message M2 and         specifies post location PL2 for message M2.     -   (C) In response to subscription A-T1, the system notifies user         client A1 that a new message (message M2) has been added to         thread T1.     -   (D) The system determines that PL2 is within user C's watch area         C1 and notifies user client C1 that thread T1 is of interest.     -   (E) The system establishes a subscription to thread T1         (subscription C-T1) for user C.     -   (F) The system determines that PL2 is not within watch areas for         users D-G, and therefor does not take any further action in         regard to notifying users D-G of this thread.

Step 3: A second reply to thread T1 is created and posted as follows:

-   -   (A) User C reads updated thread T1 on user client C1.     -   (B) User C replies to thread T1 with a new message M3 and         specifies post location PL3 for message M3.     -   (C) In response to subscriptions A-T1 and B-T1, the system         notifies user clients A1 and B1 that a new message (message M3)         has been added to thread T1.     -   (D) The system determines that PL3 is within both user D's watch         area D1 and user E's watch area E1, and notifies user clients D1         and E1 that thread T1 is of interest.     -   (E) The system establishes subscriptions to thread T1         (subscriptions D-T1 and E-T1, respectively) for users D and E.     -   (F) The system determines that PL3 is not within a watch areas         for users F and G, and therefor does not take any further action         in regard to notifying users F and G of this thread.

Step 4: A third reply to thread T1 is created and posted as follows:

-   -   (A) User A reads updated thread T1 on user client A1.     -   (B) User A replies to thread T1 with a new message M4 and         specifies post location PL4 for message M4 where PL4 is not         equal to PL1.     -   (C) In response to subscriptions B-T1 and E-T1, the system         notifies user clients B1 -E1 that a new message (message M4) has         been added to thread T1.     -   (D) The system determines that PL4 is within user F's watch F1,         and notifies user client F1 that thread T1 is of interest.     -   (E) The system establishes a subscription to thread T1         (subscription F-T1) for user F.

Step 5: System handles a roaming watch area as a third reply to thread T1 is created and posted as follows:

-   -   Note: User G watch area G1 is not touched by any of the         locations of the messages above, PL1 thru PL4.     -   (A) User G is initially at roaming location RL1 (See FIG. 5).     -   (B) User client G1 updates user client roaming watch G1 roaming         data on the system server with location RL1.     -   (C) User G moves to location RL2. (See FIG. 6).     -   (D) User client G1 updates user client roaming watch G1 roaming         data on the system server with location RL2.     -   (E) User G moves to location RL3. (See FIG. 7).     -   (F) User client G1 updates user client roaming watch G1-roaming         data on the system server with location RL3. Location RL3 is         near user B.     -   (G) A fourth reply to thread T1 is created.     -   (H) User B reads updated thread T1 on client B1.     -   (I) User B replies to thread T1 with new message M5 at post         location PL5.     -   (J) In response to subscriptions A-T1 and C-T1 thru F-T1, the         system notifies user clients A1 and C1 thru F1 that a new         message (message M5) has been added to thread T1.     -   (K) The system determines that PL5 is within user watch         G1-roaming, which is currently centered on location RL3.     -   (L) The system notifies user client G1 that thread T1 is of         interest.     -   (M) The system establishes a subscription to thread T1         (subscription G-T1) for user G.

Step 6: a fifth reply to thread T1 is created and posted as follows:

-   -   (A) User G reads updated thread T1 on user client G1.     -   (B) User G replies to thread T1 with a new message M6 and         specifies post location PL6 for message M6.     -   (C) In response to subscriptions A-T1-F-T1, the system notifies         user clients A1-F1 that a new message (message M6) has been         added to thread T1.     -   (D) User G moves to location RL4, which is far away from post         locations PL1 thru PL6.     -   (E) User client G1 updates user client roaming watch G1-roaming         data on the system server with location RL4. (See FIG. 8).

Step 7: A sixth reply to Thread T1 is created and posted as follows:

-   -   (A) User C reads updated thread T1 on user client C1.     -   (B) User C replies to thread T1 with a new message M7 and         specifies post location PL7 for message M7. (See FIG. 9).     -   (C) In response to subscriptions A-T1, B-T1, and D-T1 through         G-T1, the system notifies user clients A1, B1, and D-G that a         new message (message M7) has been added to thread T1.

Alternative Embodiments

Shared Watch Areas

In various embodiments, the system is configured to define one or more shared watch areas which may, for example, not be tied to a particular user. For example, the system may be configured to define a watch area or enable a user to define a watch area for a park, (e.g., such as central park in New York City); a particular landmark; a path or trail (e.g., such as the Appalachian Trail or other hiking trail, a neighborhood, or any other suitable region). In various embodiments, a shared watch area may be defined by an area bounded by one or more electronic markers (e.g., one or more iBeacons). In particular embodiments, the watch area may be defined by a shape of the area and may, for example, include surrounding areas. In various embodiments, the system is configured to associate a plurality of users with the shared watch area (e.g., residents of the particular neighborhood, etc.).

In various embodiments, the system is configured to enable users to elect to substantially automatically subscribe to a particular shared watch area based at least in part on a user's proximity to the particular shared watch area. In particular embodiments, the system is configured to determine that a user is located in a shared watch area (e.g., based on a GPS position of the user determined from a mobile device associated with the user), and to substantially automatically subscribe the user to the shared watch area in response to making that determination (e.g., to add the shared watch area to the user's existing watch area). In such embodiments, the systems may be configured to substantially automatically unsubscribe the user from the particular shared watch area in response to determining that the user is no longer located within (e.g., or near) the particular shared watch area. In still other embodiments, the system may be configured to subscribe a user to a particular shared watch area at least partially in response to a determination by the system that a roaming watch area associated with the user at least partially overlaps with the particular shared watch area.

Proximity Message Notification

In various embodiments, the system is configured to notify a client device associated with a first user that a new thread has been posted or may be of interest to the first user via a client device associated with a second user. In particular embodiments, the system may be configured to notify the first user via the second user's client device in response to determining that the client device associated with the first user is proximate the client device associated with the second user (e.g., the client, devices are within a particular distance of one another). In various embodiments, the system may determine any suitable proximity such as, for example, within 100 feet, within 250 feet, within 50 yards, or any other suitable proximity. In some embodiments, the system is configured to transmit the notification substantially directly between client devices using Bluetooth, Low Energy Bluetooth, Near Field Communication, or any other suitable technique.

Proximity Message Relay

In various embodiments, the system may be configured to relay threads and/or messages such as the proximity messages discussed immediately above. For example, the system may be configured to relay a proximity message from the client device associated with the first user described above that has received the proximity message to one or more client devices associated with one or more third users. In various embodiments, the one or more third users may be proximate the first user (e.g., within a particular distance of the first user), but not proximate the second user described above. In various embodiments, this functionality may enable one or more threads or messages to propagate from a particular location or user to nearby users to whom the message or thread may be of interest. In a particular example, if a robbery occurs at a particular street corner, users near the corner may receive or post a message regarding the robbery, which would then be transmitted (e.g., via Bluetooth, near field communications, etc.) to one or more nearby users' client devices.

Traveling Thread

In various embodiments, threads and messages may be associated with a particularly shaped area rather than a specific GPS location. For example, a thread related to a particular crime may be associated with a circular area having a radius of one mile from the location of the commission of the crime. In such embodiments, a user having a watch area that at least partially intersects (e.g., overlaps) the circular area may receive and/or subscribe to the thread even if the actual location of the crime is not within the user's watch area.

Social Endorsement

In various embodiments the system is configured to utilize social networking data associated with a user when determining whether to subscribe that user to a particular thread. The system may be configured, for example, to determine social networking data associated with a user such as the user's friends, connections, followers, follows, contacts, interactions, etc. on one or more social networks (e.g., Facebook, Twitter, LinkedIn, Instagram, etc.). In particular embodiments, the system is configured to subscribe a user to a particular thread when that thread falls within one or more of the user's watch areas and the thread contains one or more messages that, for example, have been posted, replied to, commented on, liked or otherwise interacted with by one or more persons to whom the user is connected via one or more social networks.
